I try to focus on actual tasks and problems and make tutorials fully functional, so any beginner interested in doing one of the possible mapping tasks can read the tutorial and at the end upload new objects to OSM.

In the works I have an article about mapping small towns using GPS, that I mapped during Arok Party (a c64 event).

About OpenStreetMap

OpenStreetMap is a freely editable and usable (including download of data) map of the world, mainly created by volunteers, but also supported by large imported data.

Exisitng editors for text data DjVu files are quite limited, like for example DjVuSmooth. So I've implemented a new editor in JavaScript, that allows editing both the strucutre of the text (paragraphs, lines, words,...) and the coordinates of the text boxes by simply dragging with the mouse, features like create, delete, merge are also available.
